,Troll wfwmzftmayconuem Y Be it'known that I, ,FREDERICK Sceau LENBERG,a citizen ofthe United States, residingV at Lima, in the county ofreellen, State of Ohio, have yinventedcertainvnew and usefulImprovements in Oil Valves; and I do hereby .declare the following to be1a full, clear., .and` enactt@descriptionY of the invention, lsi ielias, will enable 'others skilled .10 1in the art to which itiappertans to .make and use thesame. l i

This invention relates ,to new and useful improvements in lvalves andparticularly .to valves for, CQIitrolling thev flow of liquid or gaseousfuel. lThe particular yadaptation oi' 4the' valve is (for -oilorgas-burning cook :stoves 011e obj-ect. ci' the invention ist@ provide avalvev of this :character having means yfor ilimitingthe opening :andclosing movement thereof. Y

Another object of' the invention is Lto provide xa valve off thischaracter )having an 1 adjustable sto-p l'onilimitigng the openingmovement .of the-valve Aliieyond the starting position or that positionwherein l-the fuel .is permitted :to flow to the bujrner.

' 'A further object is to provide a valve with which is associatedfaSight-feed 112W- .ing a priming .means formed integrally therewith. Y YY l A still lfurther' object isto provideV .a novel valve of thischaracter having1a packiing and a -bushingso constructed 4and.arrangedthat the packinggcan `be forced `into close embracing irelationto f the stem of -the valve.

Other objectsand advantages .willbe apt parent iromzthe followingdescription when 0 taken in connection with the accompanying drawing. Yi y In fthedrawing: y i

Figure 5 is a longitudinal sectional detailed view through the handle'and locking i plunger.

`Referring particularly to the accompanying drawing 10 represents thebody of the valve which has the fuel ,inlet passage ll `extending.;inwardly from one side vand `having the threaded nipple --1 2 forattachment to the fuelmanifold 13. v Formed vertically through the bodyof the valve `is a passage 14,. VSaid passage being reduced to form theshoulder l5, on which rests ,the

stem .is formed with a tapered point 22 which .seatsin thveeconicalseat23.YV A prortion of this seat is `:formed withinthe conical boss 24,which is formed `integrally with the valve body and projects downwardlyfrom the center thereof. As clearly shown, the passage 11 communicateswith the lower portion of the passage l4,-so that when the Aneedle.valvestem 2() is elevated its point 'isfunseated, andthe fuel will passdownwardly and drop from the lower end of the boss 24. A cap nut25 isscrewedionthethrejaded neck 26, which is formedon the upper side ofthevalve body, and `is arranged t@ drive the bushing 18 downwardly,against the packing 1,6 when The Vstem 2O is vrotatably vdisposedthrough this cap.

Detachably secu-red to the upper endof the stem 20 is a laterallyextending handle 27,the same being` .secured thereto by inea-ns lof Vtheisere/w28. Secured to `the upper tace of the valve 'boi-fly, andreceiving the neck 26 upwardly therethrough, is a dial plate 29,'i1he:same beingk ,slightly Aless Lthan :a coinplete circle. This disk`secured to the valve `body by :meanscf ,the screws 30.

Formed in the dial plate 29, adjacent one end Vof the flat edge thereof,isa depression- 31, andv at a point approximately 135" from thedepression 3l is another similar depression 32. Extending radially fromthe attaching .portion of the handle,at a ,point` diametrically oppositeto the handle is an arm 33, and formed on the outer end of this arm is adownwardly extending ltubular member 34, within which is disposed thespring pressed plunger 35, the spr1ng35 of which `normally urges thelower end of the plunger into contact with the upper face of the dialplate 29, said plunderbeing arranged to drop into the said depressionBlor 32V according tothe position of thehandle and valve stem.

Projecting from the lower end oi' thetubul lar member 34 is a nose 36,to which refer:

In' the edge of the dial plate 29 are formed the series of notches 37,said series beginning at thedepression 32 and extending around from thedepression .31.

The intermediate portions of the ends 39 are outwardly and oppositelybowed as at 42 to provide a tubular socket for thecoil spring 43. The'upper end of thiscoil spring bears against the lower face ofthe dialplate 29', while its lower end bears on the upper ledge of thehorizontal leg of the L-shaped'member 41, to rock said L-shaped memberand engage its lvertical leg in one or another of the notchesl thisbody, and extending-laterally `and then Vcurving upwardly, is the pipe48, ,which `has its upper end enlarged into the form of a cup or bowl49. Into this cup or bowl 49V is adapted to be poured oil or Agasoline.for the purpose of primingthe burner, with which the Vvalve is used. Aremovable .closure -or this cup consists oi'a fiat disk 50 Vhavingdependingleg's 51, which are sofarl ranged as to rest within the mouthof the Vcup and hold the disk slightly elevatedthereabove, to permit airto pass through the cup. Screwed into the lower end of the body 45 isthe oil conveyingrpipe 52, which conveys oil to the burner. Y
